Introduction - Manual Conventions
Introduction
Congratulations on your purchase of JBL LSR4300 Series Studio Monitors, the most advanced
loudspeaker system ever developed for critical listening.
We know that very few people read owner's manuals from cover to cover, so we've organized
this one
to make it easy to find the infonnation you need.
The Features section on the next page provides a
brief overview of the exceptional features of
the LSR4300 Series. It's followed by a QuickStart section, which will get you up and
running
in a matter of minutes.
Once
you've got your LSR4300 system powered up and delivering sound, you should tum to
th
e Reference section, which describes every feature and function of the LSR4300 in detail.
Finally,
we've included a number of technical appendices and specifications at the end of this
manual.
Note that this manu
al covers the model LSR4328P and L SR 4326P Studio Monitor s. Separate
owner's manuals are provided for the model LSR4312SP Subwo
of er and for the LSR4300
Control Center softwar

Features
The LSR4300 Series combines stunning sound and legendary JBL design with innovative new
technologies. The end result
is a product that is nothing short of revolutionary - a monitoring
system suitable for use in the most demanding music, broadcast, and postproduction
applications.
RMCTM Room Mode Correction
The biggest challenge for anyone producing audio is creating a mix that sounds great on all
playback systems.
If you think of a monitoring system as a kind of "lens" through which you
hear sound, the object
is to have the lens be crystal-clear and transparent so that it imparts no
coloration whatsoever to the signal being played back. However, every loudspeaker system,
no matter how well designed, interacts with the room in which it is installed. Lack of correct
acoustic treatment (or, worse yet, lack
of any treatment at all) can result in anomalies such as
resonant frequencies and low-frequency "standing waves" -the aural equivalent to the lens
being "smeared." Trying
to create a mix in such an environment can be as fmstrating and
difficult as trying
to paint a masterpiece while blindfolded.
JBL's exclusive second generation
RMCTM Room Mode Correction technology is designed to
solve the problem. A powerful onboard computer
in each LSR4300 Series monitor
automatically analyzes the frequency response
of your room and compensates for low
frequency inaccuracies
in the listening space by precisely inserting filters so that low
frequency signals arrive at the mix position with the intended frequency response. In effect,
the LSR4300 Series goes "beyond accurate," allowing you to eliminate the guess-work and
create reliable mixes that translate
to any environment. Additionally, the RMC system trims
the level
of each speaker to compensate for differences in placement relative to the mix
position, ensuring balanced mixes.

Introduction - Features
HiQnetTM Networking
The LSR4300 Series also incorporates the new Harman HiQnet™ protocol that networks all
the speakers
in a system together and allows full control from the provided wireless remote
control or from any computer via a standard USB connection and LSR4300 Control Center
Software. With the push
of a button or the click of a mouse you can change the system level,
choose from any
of three different inputs (one analog and two digital), mute and solo
individual speakers, and make low and high frequency EQ adjustments.
LSR Linear Spatial Reference Design
The LSR4300 builds on the Linear Spatial Reference technology that has made our LSR6300
Series
of studio monitors so popular in recording, broadcast, and postproduction facilities
worldwide. The exact geometry
of the wave guide, the interaction of the woofer and hveeter,
and the final assembly
of the injection-molded parts has been redesigned fTom the ground up
to provide accurate off-axis as well as on-axis listening, within a window of +1-30 degrees
horizontal, +1-
15 degrees vertical. Attention to these critical aspects results in neutral mid and
high frequency response at the mix position and a sound which
is smooth and accurate in a
wide variety
of acoustic spaces.
Surround Smart
The LSR4300 Series is ideal for sUlTound sound use. Up to eight main speakers -any
combination
ofLSR4326 6-inch and LSR4328 8-inch models -and up to two LSR4312SP
subwoofers can be easily configured for LCRS,
5.1,6.1, 7.1 SODS and larger mixing and
monitoring applications.
Once all LSR4300 monitors are
in place, RMC and HiQNet automatically aligns the entire
system, setting relative volume so that the sound from all channels
is balanced when it arrives
at the mix position. The end result
is precise imaging regardless of each monitor's actual
physical placement.
In addition, the ability to centrally control the volume
of all the speakers (via the supplied
wireless remote control or LSR4300 Control Center software)
is particularly useful in
surround sound applications where the recording system does not provide a multi-channel
monitor volume control, or where adjustable volume is not available when using the
mixing system's digital outputs. Similarly, the ability
to selectively mute or solo channels and
to remotely switch between three digital and analog input sources enhances system capabilities
by allowing you to monitor not only the main recording system, but also any two additional
connected sources such as DVD and CD players, multi-channel processors and encode-decode
units. This alleviates the need to purchase additional outboard monitoring hardware.
Selectable Inputs
In this age of digital workstations and control surfaces, it isn't enough to simply provide an
inputjack. The LSR4300 offers three separate inputs: stereo high-resolution 96
kHz AESI
EBU and SIPDIF digital inputs, as well as dual balanced analog XLR and l i4 -inch inputs with
selectable +4dBu 1
-1 OdBV sensitivity. This allows it to accommodate a wide range of input
sources, including digital workstations,
CD players, DVD players, and multi-channel proces-
sors. What's more, you can easily select between inputs with the push
of a single button (on
either the front panel or the wireless remote) or click
of a mouse (via an attached computer and
the included LSR4300 Control Center software).

Introduction - Features
Onboard Bi-amplification
LSR4300 Series monitors are self-powered, eliminating the need for external amplifiers.
Perfectly matched bi-amplification is provided onboard, with 150 watts
of power for the
woofer and 70 watts
fo r the high frequency transducer.
OtherFeatures
Custom designed transducers specially engineered to deliver clean, crisp sound. The
LSR4328P model features an 8-inch low frequency woofer, while the LSR4326P
model offers a 6.25-inch woofer, both coupled with a I-inch soft-dome high frequency
transducer. All transducers are self-shielded, with Neodymium motor structures for
exceptional transient response and superb power handling.
Advanced front-panel user interface allows control
of system functions such as
volume, input selection, user EQ and EQ presets, RMC calibration and bypass,
individual speaker solo, and brightness level
of the meter and buttons.
Front panel meters show continuous output levels in dBFS
to serve as a visual
reference
of the speaker's contribution when measured at the mix position.
Integrated mounting points allow wall mounting
of speakers when space limitations
prohibit the use
of speaker stands.
Built-in side handles make positioning and transporting
of speakers easier.

Quick Start
Quick Start
Each LSR4300 speaker includes:
One speaker
CATS networking cable
AC power cord
This owner's manual
The LSR4326IPAK and the LSR4328PIPAK include:
Two speakers, each with the above items
LSR4300 Accessory Kit containing:
o Calibration microphone and mic clip
o Infrared wireless remote control
o LSR4300 Control Center Software
o 16-foot USB Cable
o Two network terminators
o Two AAA Batteries
Here are simple step-by-step instructions to get you up and running quickly:
1. Unpack the speakers. To avoid damage to the speaker elements, open the top of the box,
keep the Styrofoam end cap on, and roll the box upside down. The box can then be slipped
off. (This also works in reverse for repacking the units.)
II Be sure to not grasp the monitors from the front. A stray hand or finger can cause
damage to the high frequency transducer that is located near the top of the cabinet on the
front baffle.
2. Position each speaker in the room. (See page 20 in this manual for speaker
placement tips.)

3. Connect each speaker to a suitable power source using the supplied AC power cable.
(See page 23
in this manual for more information.)
4. Connect the speakers together in any order using the supplied CAT5 cable. Plug one end
of the cable into either of the two HiQnet ports on one speaker and the other end into a
HiQnet port on another speaker until all speakers are connected. Connect the
t\~o supplied
ethernet terminators to the first and last speakers
in the chain. (See page 21 in this manual
for more information on networking your LSR4300 monitors.)
5. Set the
Nework ID DIP switch on the rear panel of each speaker so that it corresponds to
the channel for which the speaker is to be used. For example, place the DIP switch labelled
LEFT
in the up (ON) position for the speaker reproducing the left channel, and place the
DIP switch labeled RIGHT
in the up (ON) position for the speaker reproducing the right
channel. (See page 22
in this manual for more information.)
II Make sure that one. and only one. DIP switch is placed in the up (ON) position for each
speaker. One speaker in the system must have the LEFT DIP switch set to the ON position.
6. Make all required audio connections to the rear panel of your monitors. Both the
LSR4328P and LSR4326P models are both able to acconunodate one analog and two
digital input signals. (See page 23
in this manllal for more information on audio
connections.)
a. If YOll are connecting an analog signal (i.e. from the line level analog outputs of a
mixing console, workstation, CD player, or DVD player), use appropriate cabling
to make a connection be
ween the device and either the rear panel Analog XLR
connector or Y4 D connector, then set the rear panel Input Sensitivity switch to

Quick Start
+4dBV (switch IN) or -IOdBu (switch OUT) to match the nominal level of the
signal source.
If you don't know how to set the switch, consult the documentation
for the signal source. Most professional devices operate at +4dBV while most
consumer devices operate at -I
OdBu. (See page 23 in this manual for audio con-
nections and wiring diagram.)
~ Do NOT mak e connections to both the XLR and % analog connectors; use one or
the other.
b. If you are connecting digital signals (i.e., from a digital console or workstation,
or from the digital outputs of a CD or DVD player or processor), use appropriate
cabling to make a connection between the device and the rear panel AESIEBU
(XLR) or SIPDIF (phono) input
of the speaker designated to carry the LEFT
channel
(i .e., the left speaker in a stereo setup). Then use appropriate cabling to
make a connection between the rear panel AES /EBU (XLR) or SIPDIF (phono)
output
of the left speaker and the rear panel AES /EBU or SIPDIF input of the
speaker designated to carry the RIGHT channel (i.e., the right speaker
in a stereo
setup). (See page 24 in this manual for a wiring diagram.)

Quick Start
8. Power up your signal source, then press the front panel POWER button on any speaker.
All speakers in the system will power on (the
JBL Logo will go from dimly to brightly lit.)
9. Set the initial speaker volume by pressing the + / - controls on any speaker. All
speakers
in the system will go to the designated volume. As the volume is increased,
additional LEDs light.
We recommend beginning with a modest volume setting, so that
only the first ten LEDs
or so (up to the "-20") mark are lit.
10. Playa signal source and adjust the final speaker volume to a comfortable listening level by
pressing the +/ - controls on any speaker.
II. If your LSR4300 system is brand new, the RMC button on the front panel of all speakers
will be lit, indicating that Room Mode Correction has not yet been perfonned.
To
calibrate your speakers with RMC, begin by attaching the provided calibration
microphone
to a mic stand and place the mic at the mix position, oriented vertically.
Then connect the microphone
to the Left speaker's RMC MIC rear panel input.
II To perform an RMC analysis, the calibration microphone must be connected to the
speaker designated as "Left" (LEFT DIP switch up).
12. Press and hold the RMC button on any speaker, then walk to a spot in the room where you
are not blocking the path between the microphone and any speaker. Each speaker will emit
a reference tone
in tum and its meter will show a left-to-right "chas e" pattern that
indicates the system is calibrating.
Wh en th e ' chase" pattern on the meters stops, the
process
is complete. You can compare the effects of RMC with the uncorrected re spon e
by pressing the RMC button on the front panel
of any speaker. When the button is lit,
RMC correction
is being bypassed and you hear the uncorrected response; when th e RMC
button is unlit, the RMC is active and compensating for any acoustic de fi ciencies in your
li stening environment. (See page 24 in this manual for a step-by-step description of the
RM C calibration procedure.)
II The RMC procedure produces a fairly lo ud swept sine wave calibration to ne that can
surprise you when you hear it for the first time. After pre ssi ng th e R MC b utt on, move aw ay
from the speaker. There is a five second delay prior to th e s ounding of the calibration tone.
13. Place the provided batteries in the wireless remote control, and, if you want to
establish computer control over your LSR4300 system, make a USB connection between
your computer and the
LEFT speaker and then install the provided LSR4300 Control
Center Software.
14. Finally, put on some good music to listen to and take a few moments to read the rest
of
this manual to acquaint yourselfwith all the features of your JBL LSR4300 system.
Enjoy!

The meter has 31 three-color segments that can illuminate in green, amber or red. For many
of the above operations, all 31 segments light green only. However, when audio signal is
being reproduced
by the speaker, all three colors are used and the meter is calibrated to
indicate the continuous output in decibels (dB) below the
speaker's full output capability.
Green
LEOs indicate signal 8 dB (or more) below clipping; amber, approximately 7 to 4 dB
below clipping; and red, approximately 3 to 0 dB
below clipping. The segment furthest to the
right ("0") illuminates red
when the input signal is has reached its maximum value (greater
than -1.5 dBFS) and causes clipping
of the electronics.

PDIF digital orAES/EBU digital). To s I ct an in put source, press th e
INPUT button.
It will fl ash and the meter display will con tinn the currently selected in put
sourc .
In addition, incoming signal wi ll temp or arily be muted. While th e INP UT button
is
fl ashing (for approximately 3 seconds), you can use the +1 -buttons to change the input
source. The newly selected input source will
th en be con fi rmed on the meter displa y, and
aft r brief pause, the input signal will resume.
To maintain the same input source and
cancel the operation, either press the INPUT button a second time or wait
fo r the 3-8 cond
"
ti me-out" to end without pressing the +1- buttons.

il. +/- - These increment/decrement buttons have different functions, depending upon
whether a front panel button
is flashing or not. If a front panel button is flashing, they are
used
to increment or decrement the value of the selected parameter. (For example, if the
PRESET button is flashing, the +/- buttons step through the various eqltalization presets.)
If no front panel button is flashing, the +/- buttons adjust the overall system volume.
(Press the + button to increase system volume and the -button
to decrease system
volume.)
In addition, by pressing both the + and -buttons at the same time, they can be used to alter
the brightness
of all front panel buttons and the Meter Display. There are six settings; at
the lowest setting, all buttons and meter segments are completely off, and only the JBL
logo glows to indicate power.

9. Harm an H iQnet connectors (RJ45 x 2) -Used to interconnect LSR4300 speakers
together for centralized system control from any speaker
or the provided wireless remote
conh'ol
or LSR4300 Control Center Software.
10 . USB connector -Universal Serial Bus Type I connector for computer connection when
using the provided LSR4300 Control Center software.
11 . DIP switches -These eight switches a re used to identi fy the channel being carried by
each speaker in a networked system. If one of the two digit
al inputs is being
monitored,
th e DIP switch setting al so determines whether the speaker is reproducing the
left (Channel A) or
ri ght (Cha nn el B) side of the incomjng stereo sign al. In n nnal
operation, only one
DI P witch should be in the lip ("on") position for each speaker. For
more informa
ti n, see page 21 in this manual.
III DIP switches are also used to restore factory settings. See page 30 in this
manu
al for more info rm ation.
12. ACTI VE INPUT dispJay -Whenever the monitor is powered on, one of these LEOs will
be lit, indicating whether the speaker
is reproducing signal arriving at the analog input,
or one
of the two digital inputs (S / DIF and AESI BU). If one of the two digital inputs is
being used, the display also shows whether the speaker is reproducing the left (Channel A)
or right (Channel B) side
of the incoming stereo signal. For more information, see page
23 in this manual.
13. POWER connector -Accepts the supplied IEC pow er cable.
